Yunyan asked Daowu: “How does the Bodhisattva of Great Compassion [Kannon] use so many hands and eyes?”
Daowu said: “It’s just like a person in the middle of the night reaching back in search of a pillow.”
— I understand.
— How do you understand it?
— All over the body are hands and eyes.
— What you said is all right, but it’s only eighty percent of it.
— I’m like this, senior brother. How do you understand it?
Daowu said: “Throughout the body are hands and eyes."

Nansen saw monks of the Eastern and Western halls quarrelling over a cat. He held up the cat and said, "If you can give an answer, you will save the cat. If not, I will kill it." No one could answer, and Nansen cut the cat in two.
That evening Joshu returned, and Nansen told him of the incident. Joshu took off his sandal, placed it on his head, and walked out. "If you had been there, you would have saved the cat," Nansen remarked.

3rd koan:

Yunmen was once questioned by a monastic "What does it mean to 'go beyond' the Dharmakāya? "
– It is not difficult to tell you about going beyond it. But how do you understand the Dharmakāya itself?
– Master, please show me an example.
– I will give you an example. But first, how do you understand the Dharmakāya itself?
– It's just as it is.
– This is what you learned in the monastics' hall. Let me ask you, does the Dharmakāya eat rice?
The monastic could not respond.
